iFixit’s detailed teardown illustrates just how difficult it is to open the Surface. For starters, there are no screws, proprietary or otherwise, on the outside of the laptop. Instead, the laptop is literally welded together using a type of “plastic soldering” that is rare to see in consumer electronics.

Anyone hoping to get inside the “beautifully designed and crafted” computer will have to pry it open with a knife or dedicated pick in order to defeat Microsoft’s plastic welding. Whether or not it’s actually worth going through the trouble of defeating said welding is another matter, given that the “glue-filled monstrosity,” as iFixit dubs the laptop, has none of the user-upgradeable parts you’d want to see in a PC, like memory or storage.

“It literally can’t be opened without destroying it,” the repair company concludes.

“If we could give it a -1 out of 10, we would,” iFixit said in an emailed statement on Friday. “It’s a Russian nesting doll from hell with everything hidden under adhesive and plastic spot welds. It is physically impossible to nondestructively open this device.”

The Surface laptops, perhaps with the exception of 2012’s Surface RT, have earned generally positive reviews, with critics variously commending Microsoft (Microsoft!) for designing attractive-looking hardware that doubles as a reference point for its vision of what a modern Windows-based laptop should look like. Unfortunately for consumers, this seductive vision is apparently incompatible with being able to extend the laptop’s useful lifespan on your own.
